A number of exercises this semester use the evals.sav file. This file, already in SPSS format, contains teaching evaluations of "TAs" by 1,848 undergraduate students. The evaluations are from a single long semester and are effectively anonymous since I have removed or altered any revealing information. 

Each line in the evals.sav file includes the responses of each of the 1,848 undergraduate students. The large number of missing figures in the file (indicated by the period symbol) resulted from students who marked or erased their answer sheets improperly. The students evalutated TAs in the following courses (course number precedes course description):

• 100 Freshman Composition 1
• 101 Freshman Composition 1 for International Students
• 102 Freshman Composition 1 on Computer
• 103 Freshman Composition 2
• 104 Freshman Composition 2 for International Students
• 105 Freshman Composition 2 on Computer
• 106 Freshman Composition 2 for Texas Academy of Math and Sciences
• 107 World Literature 1
• 108 World Literature 2
• 109 Literature for International Students 1
• 110 Literature for International Students 2
• 111 Technical Writing 1
• 112 Technical Writing 1 for International Students
